The PLATO Mission
Heike Rauer, Conny Aerts, Juan Cabrera +842
PLATO (PLAnetary Transits and Oscillations of stars) is ESA's M3 mission designed to detect and characterise extrasolar planets and perform asteroseismic monitoring of a large numb…
Identification and characterization of 15265 super-Nyquist frequencies in 1309 δ Scuti stars from Kepler photometry
Yanqi Mo, Weikai Zong, Xuan Wang +5
The frequency of pressure (p) mode in ~Scuti stars can exceed the Nyquist limit of \textit{Kepler} long-cadence photometry. {These 'super-Nyquist frequencies' (SNFs) are observ…
The TESS Input Catalog and Candidate Target List
Keivan G. Stassun, Ryan J. Oelkers, Joshua Pepper +17
The Transiting Exoplanet Survey Satellite (TESS) will be conducting a nearly all-sky photometric survey over two years, with a core mission goal to discover small transiting exopla…
EXOTIME: searching for planets around pulsating subdwarf B stars
Sonja Schuh, Roberto Silvotti, Ronny Lutz +27
In 2007, a companion with planetary mass was found around the pulsating subdwarf B star V391 Pegasi with the timing method, indicating that a previously undiscovered population of…
Asteroseismology of exoplanets-host stars: a link between the two scientific programmes of COROT
Sylvie Vauclair, Matthieu Castro, Stephane Charpinet +5
Studying the internal structure of exoplanets-host stars compared to that of similar stars without detected planets is particularly important for the understanding of planetary for…
Asteroseismology of white dwarfs in the 2040s
Murat Uzundag, Ingrid Pelisoli, Stephane Charpinet +6
White dwarfs, the final evolutionary stage of the vast majority of stars, serve as critical tools for cosmochronology, studies of planetary system evolution, and laboratories for n…
K2 photometry on oscillation mode variability: the new pulsating hot B subdwarf star EPIC 220422705
Xiao-Yu Ma, Weikai Zong, Jian-Ning Fu +4
We present an analysis of oscillation mode variability in the hot B subdwarf star EPIC~220422705, a new pulsator discovered from ~days of {\em K}2 photometry. The high-qual…
PB 8783: the first sdO star suitable for asteroseismic modeling?
Valerie Van Grootel, Suzanna K. Randall, Marilyn Latour +5
Pulsating hot B subdwarf (sdB) stars, which are core-He burning objects, are one of the showcases of asteroseismology. Thanks to the combination of rich pulsation spectra and state…
The Potential of Asteroseismology for Hot, Subdwarf B Stars: A New Class of Pulsating Stars?
Stephane Charpinet, Gilles Fontaine, Pierre Brassard +1
We present key sample results of a systematic survey of the pulsation properties of models of hot B subdwarfs. We use equilibrium structures taken from detailed evolutionary sequen…
Third generation stellar models for asteroseismology of hot B subdwarf stars. A test of accuracy with the pulsating eclipsing binary PG 1336--018
Valerie Van Grootel, Stephane Charpinet, Pierre Brassard +2
Context. Asteroseismic determinations of structural parameters of hot B subdwarfs (sdB) have been carried out for more than a decade now. These analyses rely on stellar models whos…
Oscillation mode variability in evolved compact pulsators from Kepler photometry. II. Comparison of modulationpatterns between raw and corrected flux
Weikai Zong, Stephane Charpinet, Gerard Vauclair
We present the second results of an ensemble and systematic survey of oscillation mode variability in compact pulsators observed with the original {\sl Kepler} mission. Two types o…
